Jennifer Lynch

Surveillance Litigation Director

As Surveillance Litigation Director, Jennifer Lynch leads EFF's legal work challenging government abuse of search and seizure technologies through the courts by filing lawsuits and amicus briefs in state and federal courts, including the U.S. Supreme Court, on important issues at the intersection of technology and privacy. Jennifer founded EFF's Street Level Surveillance Project, which informs advocates, defense attorneys, and decisionmakers about new police tools, and in 2017, the First Amendment Coalition awarded her its Free Speech and Open Government Award for her work opening up public access to police surveillance records. Jennifer has written influential white papers on biometric data collection in immigrant communities and law enforcement use of face recognition. She speaks frequently at legal and technical conferences as well as to the general public on technologies like location tracking, biometrics, algorithmic decisionmaking, and AI, and has testified on facial recognition before committees in the Senate and House of Representatives. She is regularly consulted as an expert on these subjects and others by major and technical news media.

Today the Illinois Supreme Court ruled unanimously that when companies collect biometric data like fingerprints or face prints without informed opt-in consent, they can be sued. Users don't need to prove an injury like identity fraud or physical harm—just losing control of one’s biometric privacy is injury enough. In...

In 2018, we learned that expanded biometric surveillance is coming to an airport near you. This includes face recognition, iris scans, and fingerprints. And government agencies aren’t saying anything about how they will protect this highly sensitive information.

The federal government doesn’t appear to have kept track...

So why do we know so little about it?The U.S. Department of Homeland Security (DHS) is quietly building what will likely become the largest database of biometric and biographic data on citizens and foreigners in the United States.
